Definitions

  • the invention relates to a screw cap for vessels which is resistant to overturning and secure for vessels, in particular for storage bottles containing cleaning fluids, consisting of a spout arranged on the vessel with a first two-start external thread and molded radial-spreading catches and a screw cap which can be expanded by the catches an outer shell molded widening wedges and a separate threaded piece with a first two-start internal thread, which corresponds to the first external thread of the spout, the gears of the first external thread being arranged on a ring so that they each encompass an angle of ⁇ 180 ° and do not or or only slightly overlap, are arranged between the radially spreading catches and the ring sleepers, and the separate threaded piece, as an overturning protection, has opposite wedge-shaped incisions with abutting edges in the screwed-on state on the sleepers n owns.
  • Screw closure is known from European patent specification 0 257 481. Screw caps of this type are used to close vessels, on the one hand providing effective child safety for the screw cap.
  • REPLACEMENT LEAF should be achieved and on the other hand a simple production, in particular by an injection molding process, is possible.
  • the known screw caps have the disadvantage that the spout formed on them has an outlet opening of relatively small diameter, which is matched to the contents of the vessel and the usually desired amount to be dispensed.
  • the above-mentioned containers should be refillable today.
  • the refilling of the containers via the known screw caps is very difficult and with the help of additional elements, for example a funnel, because larger quantities of material can only be filled into the container very poorly through the relatively small dispensing opening of the spout.
  • the object of the present invention is to overcome the known disadvantages and to provide a screw cap which, on the one hand, is easy to manufacture, includes a childproof lock and, on the other hand, enables the devices equipped with this screw cap to be refilled easily and quickly, none at all additional aids are required.
  • the spout consists of a base plate carrying the ring, the catches and the sleepers, which is arranged on the vessel, and a reducer which is detachably inserted into the ring.
  • REPLACEMENT LEAF carries, into which the reducer provided with a corresponding second external thread is screwed. This provides a connection between the reducer and the ring which is also leak-proof and which can be released without aids.
  • a second embodiment has a reducer, which is connected to the ring by a hinge and essentially closes the latter in the form of a cover in the working position.
  • the working position is to be understood as the position of the reducer, in which the small discharge opening is the only opening in the vessel and the large refill opening is closed by the reducer itself.
  • the reducer has a bead which in the working position engages behind a locking edge arranged on the ring. This means that when the reducer is placed or screwed into the ring, an additional engagement of the bead behind the locking edge is required, as a result of which the tightness of the connection is increased and automatic loosening of the reducer from the ring is excluded.
  • the reducer has a substantially cylindrical shape, with one end of the cylinder being closed by a disk which has an outlet opening in its center, which has a smaller diameter than the opposite opening of the cylinder, and opens into a pouring spout which rises tubularly over the pane.

  • the upper end face of the cylinder forming the lower part of the reducer is closed by a disk 7 in a large area of the cylinder opening. In its peripheral area, the disk 7 is widened to form a toothed ring 9, the teeth of which serve for secure gripping and easy screwing of the reducer.
  • In the middle of the disk 7 there is an outlet opening 11, the diameter of which in the example is approximately 38% of the diameter of the cylinder forming the lower part of the reducer.

Abstract

L'invention concerne un système de fermeture à vis à l'épreuve des enfants et résistant au survissage, et plus particulièrement pour récipients de stockage de détergents liquides. Ledit système comporte un bec verseur prévu sur le récipient et doté d'un premier filet double extérieur (25) et d'ergots (27) moulés sur le goulot s'évasant radialement, ainsi qu'un bouchon à vis (37) pouvant être élargi par les ergots (27) et comportant des clavettes d'écartement (51) moulées sur un manchon extérieur, et un élément fileté séparé (39) présentant un premier filet double interieur (41) correspondant au premier filet exterieur (25) du bec verseur. Les spires du premier filet exterieur (25) sont prévus sur une bague (23) de sorte qu'elles décrivent un angle inférieur ou égal à 180°, et se chevauchent peu ou pas du tout. Des éléments transversaux (33) sont prévus entre les ergots (27) s'évasant radialement (27) et la bague (23), et l'élément fileté (39) séparé présente des crans cunéiformes (43) opposés munis d'arêtes de butée (45, 53) s'appuyant contre les éléments transversaux (33) lorsque le bouchon est vissé, ce qui empêche le survissage. Ce système de fermeture se caractérise en ce que le bec verseur présente une plaque de base (19) placée sur le récipient et supportant la bague (23), les ergots (27) et les éléments transversaux (33) ainsi qu'un élément réducteur (1) inséré amovible dans la bague (23).
